When you watch the new Wonder Woman movie, in theaters June 2, there’s a very pure, sincere vibe that comes across throughout and may immediately remind fans of the original 1978 Superman movie, starring Christopher Reeve. There’s a certain old-school, easygoing sincerity to that early Superman movie, and when Fandango spoke with Wonder Woman director Patty Jenkins, she confirmed that Richard Donner’s Superman was indeed the main inspiration when it came to the tone of her film.

“I worked really hard to have that happen,” she said. “I miss that kind of movie and this felt like a perfect place to be old and new again in that way and say, ‘Here’s the grandam of superheroes and here’s her story and here’s how she made us feel as little girls and here’s how she can inspire little girls today,’ you know? In a very pure and straightforward way. I’m so happy that people have noticed that. Sometimes they haven’t, sometimes they’re just commenting that she’s hitting the same buttons that Christopher Reeve did, which is like a dream come true. It’s everything that we went for. That was the big inspiration.”

Superman wasn’t the only iconic hero Jenkins looked to while crafting her characters. When it came to Chris Pine’s Steve Trevor, she had another movie character in mind.

“For the Steve Trevor part of the story, I really drew from Indiana Jones,” she said. “He stays a man, is funny, and is like an everyman that we love and we root for, but one that’s actually not uncomfortable adjusting to a new, different kind of woman. So, Indiana Jones was a big inspiration.”

Finally, Jenkins cites one of the most well-known movies of all time when it comes to the love story between Wonder Woman and Steve Trevor.

“Then adding the two things together, Casablanca,” she said. “I wanted a great love story where both characters have integrity and it might be set in the complexity of war, but it turns into a grand love story.”

See if you can spot the similarities between Superman, Indiana Jones,Casablanca and Wonder Woman when the film hits theaters June 2. We’ll have much more with director Patty Jenkins, so stay tuned!
